Transversus Abdominis Muscle 02

The transversus abdominis muscle (transverse abdominus, transversalis muscle, and transverse abdominal muscle) is a muscle layer of the anterior and lateral (front and side) abdominal wall which is deep to (layered below) the internal oblique muscle. It is thought to be a significant component of the core. The transversus abdominis (TVA) helps to compress the ribs and viscera, providing thoracic and pelvic stability.
